Okay you magnet scientists out there, here is a tough one.
I would like to have a massive floating metal bird in my art project. I would like the bird to way about 2000 pounds and have dimensions of 6 feet long, 4 feet wide and 2 feet high.
The higher I can get this bird to float the better. I would like it to float at least 2 feet in the air.
From my research, Neodymium is the strongest permanent magnet material. But the largest magnets made of this material are less than 6 inches. I am sure the manufacturing process in not simple and thus the small sizes.
Of course if what I am asking for is theoretically impossible, I will accept a smaller bird and a lower levitation.
Since this is an art piece, I want it to last forever without an outside power source, so electromagnetic solutions almost out of the question.
Please do not let the cost of your proposed solution prevent you from suggesting it; even if it would cost millions.
The base of the artwork that the bird floats above can be made of anything you suggest. The bottom of the bird and the top of the base can be loaded with repelling magnets. We can use any materials to separate the magnets so that they do not offset each other if we need to use many magnets on the bottom of the bird.
